  Adjust the Acknowledgment: If the vendor has acknowledged a different quantity, you may need to adjust the acknowledgment in the system to reflect the correct quantity.
  Update the PO: If the vendor is unable to deliver the full quantity, consider updating the Purchase Order to reflect the new quantity that will be delivered.
  Check for Partial Deliveries: If partial deliveries are allowed, ensure that the system settings permit this and that the acknowledgment reflects the partial delivery correctly.
